Local culture can act as learning stimulus to motivate and help students to construct the knowledge. This research aims to describe the implementation effect of local culture based electrolysis laboratory activity in improving students' conceptual achievement and knowing students' responses about this laboratory activity. Research design used nonequivalent control group design. Subject of the research was students enrolled in Basic Chemistry part two on an educational institution at Bali, in academic year 2009/2010 including two parallel classes; the one class as control group (26 students) and the other as experiment group (28 students). Collecting of data used essay test and questionnaire. Students' conceptual achievement data were analyzed by Mann-Whitney U test with 5 % level of significance, whereas, students' responses data were analyzed descriptively. The result showed that local culture based electrolysis laboratory activity was effective in improving students' conceptual achievement. The improvement of students' conceptual achievement was in medium category (% g was 31.05). The highest and the lowest improvements of students' conceptual achievement existed in anode, cathode, and electrode concept (% g was 32.64) and electroplating concept (% g was 16.36) respectively. Most of students (92.18 %) had positive responses about local culture based electrolysis laboratory activity.
